Caption: Geography, one of the four science disciplines in the U.S. Geological Survey (USGS), is responsible for building, maintaining, and applying The National Map. USGS Geography (formerly Mapping) provides scientific information to describe and interpret America's landscape by mapping the terrain, monitoring changes over time, and analyzing how and why these changes have occurred. The knowledge gained through these activities is used to model the processes of change and to predict future changes.
